More of Charlotte’s friends have been paying tribute to the teenager on social media.
Pal Emily Haynes wrote on Facebook this evening: “Lost for words and heartbroken, such a lovely, caring, happy family of which we have so many memories with.
“ just can’t believe it don’t even want to imagine how Luke and Ryan are feeling but wherever you are boys I’m sending you such a hug! Rest in heaven Claire and Charlotte you truly wonderful women.”
A man called Henry wrote on Twitter: “Such a massive loss today, you’ve been there for the past 19 years, I can’t believe you’re really gone, RIP Charlotte”.
Another friend, named only as Roma, posted: “Claire and Charlotte were some of the most lovely people I’ve ever met I cannot believe it. RIP Angels.”


 This is the first picture of the husband who shot dead his wife and daughter in a leisure centre car park this morning.
Lance Hart, 57, is believed to have used a shotgun to kill Claire Hart, 50, and their 19-year-old daughter Charlotte, before turning the gun on himself.
Officers and paramedics battled to save the two women who they found gravely injured at around 9am on Tuesday. Mr Hart was already dead, and no shots were fired by police.
Investigators raided the family home in Moulton, where one neighbour described Mr Hart as “always caring” and a “very nice guy.”
